DisplayMate posted a comprehensive review of the 5.8" Quad HD+ Super AMOLED display used in Samsung's latest flagship, the Galaxy S8. DisplayMate says that this display is the most innovative and high performance smartphone display that they have ever lab tested - and it earned DisplayMate’s highest ever A+ grade.

Samsung incorporated several innovations in this new displays. First of all of course is the "Inifinity" design - the full screen display. This display is also a high-resolution 3K (2960x1440) one and it features a new and accurate 100% DCI-P3 color gamut, certified by the UHD Alliance for Mobile HDR Premium. The native color gamut is actually larger - it has a very impressive 113% of DCI-P3 and 142% of sRGB / Rec.709 gamuts. Samsung's latest AMOLEDs are brighter than before - with a peak brightness of 1,020 nits.

DisplayMate says that in almost all the tests they did, the Galaxy S8 display showed some improvement over the display used in the Galaxy S7. The new display matches or sets new smartphone display performance records for largest native color gamut, highest peak brightness, highest contrast and highest contrast in ambient light, highest screen resolution, lowest screen reflectance and the smallest brightness variation with viewing angle

All this is not surprising. For several years now DisplayMate announced that Samsung's Super AMOLED displays are the best mobile displays on the market - and each year Samsung manages to improve its OLED displays.

PWM issue

Too bad they are still using PWM on the display. A lot of people get eye strain and migraines from displays using PWM and also from other sources of flickering lights.

PWM isn't bad at all

If you complain about PWM of the displays, you have a personal problem. Samsung has no blame at all. This complaint reminds me of everyone who complains about the Sun being "too bright". It is never the Sun's fault!

PWM

You're wrong on this. PWM is a real issue for many people, especially those of us that spend 8-12hrs per day looking at screens. PWM causes eye strain and headaches - look it up. Some people are more sensitive to it than others. PWM on AMOLED is the reason I haven't bought a Samsung phone since Galaxy 2.

Too bright sun is a matter of

Too bright sun is a matter of imbalance, it not only may disturb eyes but burn the skin. The analogy isn't right as PWM is not an imbalance but an issue in the nature of it's light, not just unnatural but the flickering have the same straining effect on eyes despite of the particular person noticing it.

PWM

Sun might be too much not just on the eyes but for your skin, it's a matter of balance how much you need to minimize it to avoid harm. The pwm on the other hand has an issue in it's nature. Flickering light is faulty in it 's nature there is no way to balance it other than staying away from it. PWM is straining the eyes regardless of the fact people don't notice it therefore it's not so personal problem but a harmful feature.

Ignorant

PWM is a widely documented and common issue for users. No natural light source (black body radiator) flickers in such a way. Some people are more affected by it than others, but it’s not good for the eyes or brain.

PWM brightness control is just a lazy way to modulate backlight brightness. It won’t be around for long.

PWM

LOL, I guess flashing a light in your eyes really fast isn't bad at all. That sounds logical. Come-on man, wake-up! Basic logic should tell you that this technology is probably not good for you.  Remember the old CRT screens.  People were going blind looking at those all day.  They also flashed really fast. I hear Apple bought 70 million of these screens, from Samsung, for the next generation of iPhones.  Good work Apple! Now some of your users can start to experience what many Samsung users have - eye strain, headaches. Way to improve the user experience Apple!
